I recently bought a blaster for 800 bucks (paid way to much IMO). I got the bike, did an oil change, cleaned the carb, and put fresh new 32:1 premium gas with yamalube in it. The only thing I’m noticing is that first gear seems short and lacks that first gear bottom end power. But all the other gears are perfect.

Also, on a cold start. The bike won’t idle with the choke. On a cold start, when I pull the choke and it slightly cranks. Then I have to put the choke back in and...

My dumbass nephew didn't listen to me and used the quad when I didn't wanted him to and cracked the clutch side case.
Can I run a factory crack case cover with the diamond clutching or an I hooped with special parts and need to completely rebuild the clutch.
If I need to rebuild the clutch assembly what should I go with for parts?

My friend just got a blaster. When he first rode it, he noticed nothing unusual. However, when he gave it a wash with a hose. He noticed the bike would die when he kicked it into first gear, and a cloud of white smoke will form. He put a new spark plug in, it starts better. However, it still dies when kicked into first gear. Please help.

Thank you.]]>80 Psi Compression, White Smoke Cold Start. Dies when kicked into 1st gear.Sun, 17 May 2020 13:27:36 +0000http://www.blasterforum.com/threads/80-psi-compression-white-smoke-cold-start-dies-when-kicked-into-1st-gear.74882/

I became a new blaster owner on Tuesday. I got the bike and rode it very briefly. The compression seemed good (judging by the kicker), clutch seemed good, idle sounded "knocky"and low. After that day, the bike sat in my garage for about 3 days without starting.

Today when I went to start it, it would start but as soon as I kick it into first gear the engine immediately dies. I changed the spark plug, and did a compression test which (came up to 80psi), it starts up a...

I'm rebuilding my bottom end completely and I figured while i was in there i should change these worn out bushings which cause the engine to move around due to being so old. I'm looking for a source on part #90201-166L5-00 "Washer, Plate" which is #17 in this diagram. My local dealers are saying it's back ordered indefinitely. Are they discontinuing parts already?
